Claims. (Cl. 101-24) I An important object of theinvention is the provision of a new and novel dating or numbering mechanism employing perforating apparatus having a rotatably mounted perforating, head carrying the perforating dies which engage grooves formed in a roller co-operating with the dies, the dies being arranged and configurated so as to perforate the sheet,'but not entirely, where- I by the punches are still integrally attached to the web to be pressed against a surface of the web bymeans designed and arranged for that purpose.

A further object of the invention is to provide a dating or numbering mechanism which partially 2o punches through the paper leaving the punch outs integrally attached to the sheet or web, thereby preventing any punch-out or material of the web from becoming commingled with the material which comes in contact therewith, there being means provided to flatten out and bend the partial punch-outs against the web to prevent their being torn but at the same time leaving a clear perforation.

Numerous other objects and advantages will be 30 apparent throughout the progress of the following specification.

The accompanying drawings illustrate a selected embodiment of the invention and the views therein are as follows:'

Fig. 1 is a detail diagrammatic or schematic view showing the web feeding, perforatin and cutting elements and the means for operating them;

Fig. 2 is a detail elevational view of the web 4 feeding, perforating, and cutting elements and the operating mechanism therefor;

Fig. 4 is a detail sectional view on the line 4-4 45 0: Fig. 3;

Fig. 5 is a detail plan view of the perforating element looking in the direction of the arrows 5-5 ofFiSA; j Fig. 6 is a detail plan view of the web after it 50 has been punched or perforated; and p I Fig. '7 is a detail sectional'view of the web on the line 1-1 of P13. 6.

The particular dating or numbering mechanism I hereinshown for the purpose of illustrating the 55 invention comprises a frame I. upon which there is mounted a shaft ll carrying a roll 12 of webbing I3 such as parchment, paper, or other similar material. In the particular embodiment herein shown the webbing I3 is a fibrous material or parchment which is used for wrapping 5 butter, oleomargan'ne, or other similar commodity. The web or webbing 13 passes over a driven roller [4 mounted on a shaft l5. The

driven roller 14 has meshing relation with a driving gear l6 mounted on the perforator shaft 11. 10 A perforator segment 18' is fixedto .the perforator shaft l1 and carries dies l9 having a plurality of perforating pins 20. The perforating pins 20 co-operate with circumferential grooves 2i formed in the co-operating driven roll or platen 1 roll Id. The segment i8 is fixed to the shaft l1 and rotates therewith, and inasmuch as the shaft I1 is driven from the drive shaft IS, the roll it and the shaft 11 rotate at predetermined speeds whereby the die I9 is brought into perforating 20' engagement with the web '13 every. revolution of the shaft l1. Therefore, theperforation of the web can be accomplished at desired spacings on the-web, f

- The perforating pins 20 are provided with beveled edges 22, Fig. 3, so that punchings or flaps 23 will be punched from the web I3. The flaps or punches 23 will have a'n-intact portion 25 integrally connecting them .to the body of the web, thereby providing downward'y extending portions connected to the web, Fig. 7, and the perforated openings 25.

The web 13, after it is punched by the pins 20,-

passes over a driven roller 26, Fig. 1, mounted on the shaft 21. Theshaft 21 is driven by an idler gear 28,mounted on a shaft 29., The idler gear 28 .has meshing relationship. with a gear on the shaft I 5 and is driven thereby. It also has meshing relationshipwith the gear on the shaft 21 and drives the shaft 21.

Measuring feed rolls 30 and 3! mounted on shafts 32 and 33, respectively, are driven by an idler-gear 34 having meshing relationship with gears on the shafts 21 and 33. The web l3 passes between the measuringfeed rolls and feeds the 5 web to the cutters 35 and 36 mounted on the: cutter shafts 31 and 38, respectively. The cutter shafts 31 and 38 are driven by an idler gear 39 having meshing relationship with gears on the shafts 33 and 3B.' shafts 31 and 38, have meshing relationship so they are driven synchronously in opposite directions and in timed relationship with each other. The cutter-rols 35 and 36 are provided with cutters or knives I. and ll, respectivelnFil. 1.

The shafts 32 and 33, and the 5 A blade element 42 is arranged preferably between the driven roller i4 and the roller 26 and extends upwardly from its base 43, being relatively perpendicular to the web l3 as the web passes from the roll H to the roll 26. This blade element 42 has its upper surface beveled as indicated at 44, Fig. 7, with its longer edge arranged toward the oncoming web, and its purpose is to engage the downwardly hanging partially punched out pieces 23 and bend them back against the face of the webbing as indicated at 46, Fig. 7, whereby the integral contacting punch elements 23 are left fixed to the web but bent back, preventing any particles from sticking to the material which is to be wrapped in the webbing but permitting clean perforations which can be easily and readily seen and deciphered.

The invention therefore provides a simple device for feeding a parchment to perforating position where it is perforated, and then feeding it to cutting position where the cutters 40 and 4| cut the web into wrapper lengths. The entire elements from the roller l4 to the cutters 40 and 41 are operated in proper timed relationship to properly feed the web and to cut it at predetermined lengths.

During the present description it was stated that the shaft i5 could be the drive shaft, but in practice it has been found convenient, due to the location of the cutters, to drive the shaft 38, the other gears and shafts being driven from this latter shaft. However, inasmuch as all thedevices are geared together any one of the gears may be the driving gear.

The web after it is cut is provided with clear perforations, which perforations are formed by the perforating pins 20 which do not entirely cut out the paper, but leave punch-outs 23 fastened integrally to the main web I3 by the intact portions 24'. The intact portions 24 are bent over by the blade 42 and are forced back against a surface of the web. These portions when they are bent back as indicated at 4B are further pressed against the web as the web passes over the roll 26 and between the measuring rolls 30 and 3|. The pins 20 are part of the dies IS, .the dies being fixed in the segments l8, Fig.4, by the fastening or locking members 41.

i It will be seen from Fig. 5 that the perforating pins of the dies H are arranged in columns and rows to form numerals indicative of the date or number of the packaged articles. It will be evident that from day to day or from series to series, other dies, having perforated pins 20 arranged in columns and rows, may be substituted for the particular die shown, the pins 20 mating with the circumferential grooves 2| in the plate and roller l4.

The particular device herein disclosed for the purpose of illustrating the invention comprises few and simple, positively operating parts which are correlated and operate in proper timed relationship synchronously, and the arrangement of providing connected punchings or flaps prevents particles of the webbing or material from becoming commingled with or sticking to the material to be wrapped, a condition which would exist were the punchings completely severed from the material.

Changes may be made in the-form, construction and arrangement of the parts without departing from the spirit of the'invention or sacri- I flcing any of its advantages, .and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims. 4
